sem command breaks

[mactsouk]

Apart from sem version that works, sem delete project S2, sem get projects and sem get secrets break:

The output of sem get secrets is the following:

panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0x20 pc=0x13a9fb1]
